BURGLAR-PROOF SAFE.

SPECIFICATION forming part of Letters Patent No. 405,563, dated June 18, 1889.

Application filed December 24. 1888. Serial No. 294,499. (No model.)

To aZZ whom it may concern:

Be it known that I, PHINEAS F. KING, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Burglar-Proof Safes,

of which the following is a specification.

My invention relates to that class of burglar-proof safes which have circular dooropenings, and a circular door which is drawn to its seat by screw-threaded connection; and it consists in peculiar means of constructing the screw-threaded inner end of the circular door, whereby the construction is stronger, the safe can be produced at a less cost of labor and materia and the paris are more readily fitted together.

The invention will be first fully described in connection with the accompanying drawings, and will then be particularly referred to and pointed out in the claim.

In the drawings, in which like parts are represented by si in ilar reference-letters whereever they occur throughout the various views, Figure 1 is a vertical transverse sectional view of a safe-body taken through line y y of Fig. 2, showing the inside of the safe-front and the closed door in elevation. Fig. 2 is a vertical sectional view of the safe-body and closed door, taken through line :20 a: of Fig. 1.

threadedto engage the interiorly-tapped ring D, which is screwed onto the disk O. The disk and ring are locked firmly together by keys 0, which are driven into keyways cut into the ring and disk after the ringis screwed tight against the inner face of the door.

The ring D is screw-threaded exteriorly to engage an interior tap in the flanged ring E, which is secured on the inside of the safefront around the door-opening by bolts 6, which pass through the flange e of the ring E.

\Vhat I claim is- In a burglar-proof safe of the character described, the combination of the safe-front, having a circular door-opening, the interiorlyscrew-threaded ring surrounding said opening, the circular door, the screw-threaded disk secured upon the inner face of the door, the ring I), screwed onto said disk, and the keys 55 for locking the said disk and ring together.

PI-IINEAS F. KING.
